Perhaps one of the worst cars on snow, an automatic (SMG) BMW M3 with 255/35 R19 rear tyres in a "race" against various other vehicles.
The first one to the top of the small, snow covered incline wins. Traction control turned off in the M3 and always started in 1st gear. Oh, and the M3 has Michelin Pilot Alpin 4 UHP winter tyres.
In order of "race" appearance:
1) M3 vs BMW 118d Manual. Drive wheels are new 245/35 R18 Nankang NS20 summer tyres
2) M3 vs Ford KA. Drive wheels are 165/35 R13 budget summer tyres
3) M3 vs BMW 118d with extra weight over the rear wheels
4) M3 vs VW Passat Manual with an extra runup. Drive wheels are new 205/55 R16 Dunlop SP Sport summer tyres
Apologies for the quick editing.
